Specification of Letters Patent.

Patented Jan. 22, 1913.

Application led. August 3, 1917. Serial No. 184,209.

T o all whom it may concern.'

Be it known that I, FREDERICK WrLLsoN, a citizen of the United States,residing at Reading, in the county of Berks and State of Pennsylvania,have invented certain new and useful Improvements in Goggles, of whichthe following is a specification.

My invention relates particularly to goggles adapted for industrialuses, such as welding operations which require the employment ofwindowed eye-cups formed to approximately lit the face. It consists inimproved means for securing properl ventilation of the cups inconnection with eii'ective exclusion ot' objectionable light, foradvantageously securing the window disk or lens in the front of the cup,and for properly supporting flexibly connected cups when in service; asspecifically setA Jforth in connection with the accompanying drawing anddefined in the subjoined claims.

Figure 1 is a front elevation of a pair of goggles embodying myinvention in preferred form a portion of one eye-cup being Shown insection on the line 11 of Fig.

F ig. 2 is a top view partly in longitudinal section on the line 2-2 ofFig. 1.

Fig. 3 is a separate view of a ballle-plate device ot modified form; andFig. 4 shows a lens-retaining ring.

The goggles shown comprise a pair of windowed e've-cups formed withslotted lugs 2, 2 tor a flexible bridge connection 2, and similar outerlugs 3, 3 tor retaining head band 3B. lEach cup is of molded l'orm,shaped to receive an approximately triangular drop-eye disk 4, and witha correg spending eye-inclosing wall 'having an outer portion 5extending templeward, an upper portion 6 running along the eyebrow, andlower portions 7- and 8 converging below the eye. Upon the innerinclined wall portion 8 of each cup is formed a transversely rounded ribor circumferential bulge 10 adapted to lit against the respective sidesof the nose so as to eoperate with the bridge connection 2 insatisfactorily supporting the goggle in properly adjusted position.

'.l'he lens or light disk 4 is formed with a beveled edge 4, and isadapted to be linserted from the inner side of the cup so as to restmarginally upon an annular flange 12 of the latter, with the bevel ofthe lens extending inward. '.ll`he cup is formed )Vith an interiorannular recess 13 between said Harige 12 and an overhanginginclined-offset portion 14; which recess is adapted to receive a springretaining ring 15 engaging between said inclined offset 14 and thebeveled edge of the inserted lens so as to removably secure the latteragainst said flange 12.

The wall of each cup is provided with a Ventilating opening 20, which isadapted to receive a removably secured baiiie-plate device arranged tosatisfactorily provide ventilation while at the 'same time properly ob-`structing the admission of unintended light or flying matter to the cup.This separately formed device, as shown. comprises a hollow shankportion 2l insertible in the opening 20 as limited by a stop or shoulder22, and provided with a lateral air inlet or inlets 23 to the cup; and abaffle-plate cap portion 2t larger than the yopening and spaced awayfrom the cup-wallf'so as to permit passage of air between the wall andthe platethrough the openings 23. while at the same time serving as aneiective baille. The inserted device may be conveniently secured inposition by nieans of a groove-engaged spring ring 25 as indicated. Thebattle-plate 24 is preferably arranged approximatelv in the plane ot theeves and at the widened portion ot the triangular cup, and is curved toparallel the adjacent inner wall of the latter. In the modifiedconstruction indicated in lFig. 3, however, a flat battle plate 24a isshown adapted to be arranged adjacent the exterior wall of the cup.

1., A goggle eve-cup having a front window, a wall Ventilating opening,and a battle plate for said opening spaced away from the wall of the cupand overlapping the edge of the opening.

2. A goggle eve-cup having a front window. a wall Ventilating opening,and a separatelv formed battle plate for said o ening attached to thewall of the cup an oven lapping the edges ot' the opening.

3. A goggle eve-cup having a front window. a wall Ventilating opening,and a separately formed baille plate for said opening having a hollow,apertured shank portion secured in the latter.

4. A. goggle-cup having a front window, a wall Ventilating opening, anda separately formed interiorly located baille plate for said openingsecured to the cup..

5. In combination with an eye-protector mii lill@ cup having a frontwindow and a wall ventilating opening, a baille-plate device having ashouldered hollow shank portion insei'tible into said opening, and meansfor retaining 5 the inserted device.

6. An eye-protector cup for a bevelededge lens, having a front Windowopening, a lens-edge contacting flange and an inclined ,retaining-ringoffset forming between them a lens-edge receiving recess, and a springretaining ring engaging between said inclined otfset andthe beveled edgeoi' an i11- serted lens.

In testimony whereof I aix my signature.

FREDERICK WILLSON.
